RUBBER STAMP.

Refiled for abandoned application Serial No. 742 612, filed October 9,1924. This application filed September 25, 1926. Serial No. 137,809.

This invention relates to new and useful improvements in printingdevices, and particularly to rubber stamps, and is a refiling of theapplication, filed October 9, 1924, Serial Number 742,612.

In the ordinary cushion stamp, the cushion is secured, or glued within agroove or channel in the head or block of the stamp. The rubber strip,on which is molded the matter to print, is secured to the outer face ofthe cushion. It is diflicult to secure the printing face to the cushionso that the same will not become loosened, and finally become completelydetached. Damp weather causes the softening of the glue. with the resultthat the rubber is easily displaced.

The principal object of the present invention is to providemeans forsecuring the rubber printing face to the cushion, and block. so that itcannot be removed by damp air, or by hard and constant usage Anotherobject is to provide a dev ce of this character wherein the means usedfor holding the printing strip, serves also to hold the cushion withinthe groove or channel of the block of the stamp.

Other objects and advantages will be apparent from the followingdescription when taken in connection with the accompany ng drawing.

In the drawing:

Figure 1 is a side elevation of arubber stamp made in accordance withthe present invention.

Figure 2 is a view looking toward the printing face of the stamp.

Figure 3 is a sectional view on the line of Figure 2. 7

Referring particularly to the accompanying drawing, 10 represents thehead of the stamp, which is in the form of a wooden block, having alongitudinal channel or groove 11 in its working face, and to whichgroove is secured the rubber cushion 12. The ends of the cushion areexposed at the ends of the groove or channel, as is usual, and eXtending longitudinally on the outer working face of the cushion is theprinting strip 13, which has type faces formed thereon, in the usualmanner. This printing strip 13 has its ends continued downwardly at theends of the block, in covering relation to the ends of the cashion, asshown at 13, and disposed transversely of these ends 13, are the metal.

strips or plates 14, the intermediate portions of which are slightlyoffset, as shown at 14',

'to receive therein the said ends of the printing strip. Nails '15 aredriven through the ends of the plates 14, into the ends of the block,while a single nail is driveninto the center of each plate, and throughthe end of the printing strip, and into the end of the block.

The cushion is glued into the groove 11., and the printing strip gluedto the outer face of the cushion 12, in the usual manner, but by reasonof the metal plates 14, and the nails, the cushion, as well as the endsof the printing strip are secured from accidental detachment.

There is thus provided a device which is simple, durable, and effectivein construction and operation.

It will be particularly noted that the strip which contains the printingface includes a central body portion with tabs on its opposite ends. Itwill also be noted that these tab ends are inserted between the offsetintermediate portions of the metal strips 14, and the end faces of theblock 10, so that the printing body lies against the working face of thecushion 12. The printing strip is a part of a long strip containing anumber of printing portions, which are adapted to be cut apart, and oneof them secured to the block as described. Thus, by removing the centralnails 15, the old strip may be re moved, and a new strip, containing adiifereut printing face, substituted.

What is claimed is:

A hand stamp including a block, a strip of metal disposed transverselyof each end of the block and having the major portion intermediate theends offset away from the block ends and having its ends secured to saidblock ends, a printing strip including a central body portion having aprinting face and terminal tabs. said tabs being arranged to be insertedbetween the offset portions of the metal strips and the block ends. andfastening means disposed through said intermediate portions of the metalstrips, the tab ends of the printing strip, and the block ends, wherebysaid printing strip is securely fastoned to the block. while at the sametime being readily removable.
